.To all whom it may concern.-

Beit known that I, HARRY M.'PFLAGER, a citizen of the United States, residing at St. Louis, in the State of Missouri, have inventedy a newand useful Combined Car-Body Bolster and Draw-Bar Spring-Pocket, of which the following is a s eciiication.

My invention re ates to a metallic, referably cast-steel, car-body bolster lan com bined draw-b ar spring-pocket specially adapted for a low-body car, and has for its. object to enable the draw-b ar extension of the draftgear, with its yoke and springs, to be a plied to the bolster above the top member thereof and between the middle longitudinal car-sills in a horizontal planealined to that of the draw-bar and coupler at the standard height thereof from the track instead of to the body of the bolster below its to member, which necessitates an uward inc ation or curvature of the drawar extension therefrom to bar,'as at present the case.

The invention consists in features of no velty, as hereinafter described and claimed, reference being had to the accompanying drawings, forming'part of this'specification, whereon- Figure 1 is a front side elevation of my im- .proved car-body bolster and combined drawar spring-pocket; Fig. 2, a. top lan view thereof, showingthe draft-gear app ied thereto; Fi 3, a vertical longitudinal section throug the bolster, pocket, and draft-gear (seen partly in side elevation) on line 3 3 in Fig. 2; Fig. 4, asimilar view thereof (broken away) on line 4 4 in Fig. 2; and Fig. 5, a vertical transverse section through the pocket and draft-gear on line 5 5 in Fi 4.

Like letters and numerals o reference denote like parts in all the figures.

' a, represents a car-body bolster having the center-plate l-and side bearings 2 and coinposed, preferably, of cast steel integral throughout. The Abolster a in the present case is I-shaped'in cross-section, having the top iianges or tension member 3, the bottom flanges or compression member 4, and the web 5, the top member 3 bearing a ainst the under side of the middle and outer on 'tudinal sills 6 6 of the car-body, to which t e bolster ais secured by bolts (not shown) in the usual well-known manner, or the bolster 'a :by the middle web 9 into two parts 11 11', its connection with the inner end of the drawthe car, thev distance between the outer faces of the walls 8vbeing preferably equal to that between lthe middle longitudinal sills 6, against which they bear, as shown.

The walls 8 are united to each other, pref'- erably in the middle, by an upright'web or hollow wall 9 and at the top by a horizontal wall 10, which extends for a suitable distance beyond the front and rear faces of the -web 9 to preferably the' full widthof the to member 3 of the bolster a thereat, the walls 8 and 10 thereby forming with the top member 3 a draw-bar spring-pocketA b, which is divided having their openings respectively at the 7i5 front and rear sides of the bolster a. The

upright web 9 is'preferably in the planeA of the web 5 of the bolster a, the wall 10, with the webs 9 and 5 and center-plate 1,-bein perforated centrally and otherwise adapte thereat for the passage of the king-bolt (not shown) therethrough. f

In the front face of the web 9 within the compartment 11 of the pocket b are formed two horizontally-arranged and parallel cylindrical recesses or housings 12, one oneach side of and equidistant from thelongitudinal center liie of the car and adapted to receive the buffng-springs 13 of the draft-gear, and in the rear face of the web 9 within the compartment 11, ofthe pocket b are formed similar recesses or housings 12', which are alined to the housings 12 and adapted to re,- ceive the "draft-springs 13 ofthe draftgear, the springs 13 13', with the draw-bar extension 14 and yoke 15 of the draft-gear, which is s lidable through openings 16,formed therefor transversely through the yweb 5 of the bolster a, being centrally 1n the same horizontal plane with the draw-bar and couple c at the standard height thereof from the track and similar in principle and operation to the corresponding parts of the self-centering draft-gear described in the Letters Patent of the Umted States granted to me January 23, 1906, No. 810,805, for improvement TOO draft-gear for railroad-cars, or the pocket b i sills of acar-.underframa of a-bodybolster o of the bolster a may be adapted to the springs and combined parts of any other suit- Aable form of draft-gear. By the above arrangement the draw-bar extension, with its yoke and springs, being in the same horizontal plane with the draw-bar and coupler, the strain of the draft-gear is applied in a direct line to the bolster ata point 'above .its top member between the middle lon 'tudinal car-sills, as required in the case of a ow-body car for maintaining the standard height of the coupler, whereas when applied tothe bolster below its top member 1t is necessary to incline or curve the draw-bar extension upward therefrom to itsl connection with the coupler draw-bar, which not only weakens the draw-bar extension, but owing to the difference of level between the springs and coupler the draft-gear is unduly strained.

' For obviating thetendency of the bolster a to cant at the level of its top member 3 under the strain of the draft-gear when applied, as above described, the top member 3 1s formed ,on its upper side with longitudinal ribs 17, i

which are adapted to engage in correspondin slots formed transversely in the under si e of the sills 6 and 6', respectively, as

- shown, whereby any tilting stra-'1n on the bolster a thereat is transmitted to the sills 6 6,.

or in lieu of a rib 17 to each sill a single extended rib may be used on each side of the pocket b for engaving in the slots of the sills. Similar upright ri s 18 are preferably formed on the .outer side faces of thefpocket t for engaging in corres onding slots in the inside aces of the midd e longitudinal sills 6,where by the pocket b is held more firmly and play thereof prevented.

What I claim as my invention, and des-ire to secure b Letters Patent, s j

v1. A carody bolster ofthe class described, having a pocket projecting -upward therefrom' at its middle portion and integral therewith, the' said pocket being adapted inter- I nally to form a housing for suitable draftgear, substantially as described and for the purpose 'set forth. j

2. ',lhe combination with the longitudinal composedfofsuitable metal and iixed to the said sills, a pocket rejecting upward from the bolster at its mi d-le portion and adapted internally 'to form av housing for suitable draft-gear,- the said housing being in central horizontal al'inement with the draw-bar and cou ler of the said gear, substantially as descri d and for the purpose set forth.

3. The combination with the longitudinal sills of a car-underframe, of a body-"bolster composed of'suitable metal integral throughout and fixed to the .said sills, a pocket projecting upward from and integral with the topmem er of the bolster at its middle portion, and adapted internally to form a housing for suitab e draft-gear, the said housing being in central horizontal alinement with the draw-bar and cou ler of the said gear, substantially as descri ed.

4. The combination with the longitudinal sills of a car-underframe, of a body-bolster composed of suitable metal andfixed to the said sills, a pocket rejecting upward from the bolster at its mi d'le portion and adapted internally to form a housing for suitable draft-gear, the said housing being in vcentral horizontal alinement with the draw-bar and coupler of the said gear, and ribs projecting from the top of the bolster and ada ted to engage in the said sills, substantia ly as described and for thepurpose set forth.

5. The combination with the longitudinal sills of a car-underframe, of a body-bolster composed ofvsuitable metal and fixed to the said sills,'a pocket rojecting upward from the bolster at its mi' dle portion and adapted ,to bear at its sides against the middle lon itudinal sills, and'ribs rojecting from t e "said sides for en aging t e said'middle sills,

the said pocket eing adapted internally to form a housing for the sprin s of suitable draft-gear, substantially as escribed and for the purpose set forth.
